High temperature blast erosion test method and high-temperature blast erosion test apparatus

摘要

PROBLEM TO BE SOLVED: To provide a method and device for a high-temperature blast erosion test that can measure an erosion amount with a high accuracy.;SOLUTION: The present invention relates to a method for a high-temperature blast erosion test that includes introducing solid particles into an acceleration nozzle 2 for accelerating a fuel gas and injecting the fuel gas and blowing a fuel gas 60 containing the solid particles to a test piece 50. During the test, the temperature of the test piece 50 is kept to be constant in such a manner that the fuel gas 60 containing the solid particles is intermittently hit against a blowing surface 50f while the test piece 50 is being heated by a temperature keeping device and also while the acceleration nozzle 2 is being reciprocated in an amplitude range beyond the blowing surface 50f into one direction of the blowing surface of the test piece 50.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
